The open source browser is available for Mac, Windows, iOS and Android. Brave is run by javascript creator and Mozilla cofounder Brendan Eich.

Researchers from Perception Point published a blog post Tuesday describing a vulnerability in Linux Kernel version 3.8’s OS keyring that can escalate a local user to root privileges. Oversimplified a leak happens when a process tries to replace its current session keyring with the very same one, and then a memory overflow can free the keyring object. The bug affects PCs, servers and an estimated 66% of Android devices. The researchers privately reported the bug to Linux kernel mainatiners and fixes are on the way, so keep your patches up to date folks!

Pick of the Day

I thought you would be interested in this Freakonomics episode on "How to Be Less Terrible at Predicting the Future".

They talked about many interesting topics such as "vague verbiage" (how an ambiguous statement like "fair chance of success" by the Chiefs of Staff almost affected JFK's decision to invade Cuba when "fair chance" actually meant only one in three) and "superforecasters" (how ordinary, outsider people with the right attitude can outperform the full-time professionals). The whole episode is worth listening to.

Cheers,

Hi

I watched an interesting news story on Norwegian television two days ago where a local fire department was talking about how important drones can be when putting out fires. This particular news story was triggered by a fire close to a few storage container filled with explosives, 35 metric tons of high explosives (38,5 short ton for you US-guys). The local fire brigade launched a drone to get a good overview of the situation and monitor the fire while evacuation everyone within a radius of 1 km (0,6 miles). They managed to monitor the fire and the radiant heat until it burned out by itself and they could safely enter and secure the area.

More details, pictures and a video here: http://www.fvn.no/lokalt/sogne/--Det-har-vart-betydelig-fare-for-eksplosjon-2953181.html (sorry, only in Norwegian…but you don’t need to know Norwegian to check out the images)

In yesterday's show you had a pilot being skeptical about autonomous cars because he was comparing cars with autonomous aircraft. However, I would argue that this is a faulty comparison. Cars and aircraft have a totally different "factor of safety" when designing them. Aircraft typically have a factor of safety of 1.5 where cars are around 4. This means you figure out how much stress a component should take and multiply it by that fudge factor, oops I mean factor of safety ;-)

So it is not just public perception that makes aircraft systems more stringent but the fact that they can take less error. So if you are comparing autonomous aircraft to autonomous cars, I would say that shows autonomous cars are just around the corner. Cars can accommodate more weight and thus more safety systems. And since the speeds are far slower than aircraft, the stress levels are smaller too.

Just looked at the year-end financials (attached) for Netflix after listening to Tuesday’s show. Costs in general are historically in line and the main bump in EPS seems to be from tax benefit rather than operations, so I don’t think it is something to get too excited about for Netflix in general. Only 3.3% of revenues is left after their costs of revenues, marketing, technology, and administrative costs.
